ABSTRACT:
A vehicle alarm system for notifying a caregiver when a child is seated inside an existing vehicle may include a portable controller carried by the caregiver and a stationary controlled situated within the vehicle. The stationary controller may include a fluctuating threshold operating parameter updating mechanism as well as an emergency signal emitting mechanism. The updating mechanism compares the occupant's body temperature with the maximum and minimum temperature thresholds. Such threshold depends on the air temperature inside the vehicle. If the body temperature is above or below such save limits, the updating mechanism notifies the emergency signal emitting mechanism which relays the information to the portable controller. The emergency signal emitting mechanism also includes sensors that activate the system when the vehicle ignition is turned off. Further, emergency signal emitting mechanism produces an alert signal if the seatbelts remain locked, signifying a remaining occupant in a parked vehicle.
